1. (a) Upon written request, the Commission's staff will furnish a description in words of the Commission's jurisdiction. Upon written request and upon submission by any person of a map at an appropriate scale and showing sufficient topographic data, the Commission's staff will indicate upon such map or a copy thereof the location of the Commission's jurisdiction or of any particular boundary in a particular area represented by one or more of the San Francisco Bay Plan Maps.
2. (b) Upon written request from any person who has obtained a map or description as provided in the preceding paragraph, the Commission shall by resolution determine by map or in words the location of the Commission's jurisdiction.
3. (c) These maps or descriptions in words need not be based upon surveys performed for the Commission, but may be based on any reliable sources available.

4. (d) The Commission shall determine its jurisdiction based on existing conditions if the nature of an area has changed:

   1. (1) as authorized by a Commission permit, except as provided in section 10710;
   2. (2) as the result of the failure to maintain any use of land or water or any human-made works, including any structure, dike, levee, tide gate, or other water-control structure;
   3. (3) as the result of the natural destruction of and failure to timely repair any human-made works, including any structure, dike, levee, tide gate, or other water control structure, except as provided in section 10123(a); or

   4. (4) as the result of an area becoming subject to tidal action due to periodic inundation with tidal waters or sea level rise.

      For purposes of subsection (3) “timely repair” means within one year after the event or occurrence causing the natural destruction of the human-made works or, if the affected property owner submits within 180 days of the event or occurrence a written request to the Commission for additional time and provides an estimate of the time that will be reasonably necessary to complete the repairs, for such longer period of time as may be specified by Commission resolution to be timely under the circumstances.
